A new study finds infants and preschoolers who don't get enough sleep at night are at increased risk for later childhood obesity.

Researchers also found that daytime naps are not an adequate substitute for lost nighttime sleep in terms of preventing obesity.

Scientists reporting in the journal Archives of Pediatrics and Adolescent Medicine say the findings suggest there is a critical window prior to age 5 years when nighttime sleep may be important for subsequent obesity status.
